embodiment

[0080]FIG. 1 depicts a block diagram showing a functional structure of a degree of interest estimating device according to an embodiment of the present invention.

[0081]A degree of interest estimating device 100 estimates a degree of interest of a user (viewer) in a video shown on a screen.

[0082]As shown in FIG. 1, the degree of interest estimating device 100 includes an eye gaze detecting unit 101, a saliency information obtaining unit 102, and a user response analyzing unit 103.

[0083]The eye gaze detecting unit 101 detects an eye gaze direction of the user. In other words, the eye gaze detecting unit 101 detects the direction in which the user is looking.

[0084]In the embodiment, the eye gaze detecting unit 101 further calculates a gaze coordinate system indicating, on the screen, a movement locus of a position at which the user is gazing. Specifically, based on the gaze direction and the position of the user, the eye gaze detecting unit 101 calculates, as a gaze position, a point a...

Abstract

An interest degree estimating device, which estimates a degree of interest of a user in a video displayed on a screen, includes: an eye gaze detecting unit for detecting an eye gaze direction of the user; a saliency information obtaining unit for obtaining saliency information on a saliency area having salient attractiveness in the video; and a user response analyzing unit for calculating a correlation between the saliency area specified from the obtained saliency information and the detected eye gaze direction, and estimate the degree of interest of the user in the video, the degree of interest being higher as the calculated correlation is higher.

Description

TECHNICAL FIELD[0001]The present invention relates to a degree of interest estimating device and a degree of interest estimating method for estimating a degree of interest of a viewer (hereinafter also referred to as “user”) watching a displayed video.BACKGROUND ART[0002]In this day and age of the information explosion with abundant information, people's interests have become diverse. Consequently, it is getting more and more difficult to win the hears and minds of users with conventional and uniform techniques for presenting information. Thus required today is a technique to present personalized information; that is, casually conveyed information of the users' potential interests.[0003]For example, the number of channels for a TV as a display device is rapidly increasing along with the digitalization of the recent TV broadcasting. So is the number of content items distributed via the Internet. As a result, a user can select a content item from among a large number of content items....
